lSPINNING-SPINDLE AND BOLSTER THEREFOR.

SPECIFICATION forming part of Letters Patent No. 357,066, dated February1, 1887.

' Application filed October 19, 1886. Serial No. 216,660. (No model.)

To all whom it may concern:

Beit known that JOHN D. COLBY, (deceased,) late of Lowell, in the countyof Middlesex and State of Massachusetts, did during his lifetimeinventcertain new and useful Improvements in Spinning-spindles andBolsters Therefor, of which the following is a specification.

The obj ects which the Said COLBY hadin view were to simplify and lessenthe cost of construction of the devices inquestion, and to so constructand arrangesaid devices as to permit the spindle to be run at high speedwith the least possible vibration. It was in furtherance of theseobjects that he devised the invention for which Letters Patent No. 342,581,were issued to him on the 25th of May, 1886, the leading feature ofsaid patented invention consisting in combining the bolster-tube with anexternal supporting-tube therefor, and atransverse web connectingtogether the two tubes, the construction being such that the bolstermight bev slightly deflected from .the axis of the supporting-tube toaccommodate itself to the' spindle.

The present improvement is in the line of the patented inventionreferred to, and has in view the suppression of the evil effects of thegyratory movement of the bobbin'or spindle, which is apt at times totake place when the plained and understood by reference to thevaccompanying drawings, in whichM Figure l is a vertical central sectionof ,a bobbin, spindle, and bolster embodying the invention in itspreferred form.- Fig. 2 is a perspective view of the spindle.

A represents a portion of the rail of a spindle-frame; B, the spindle,having a whirl, C, attached thereto, and D the bobbin'carried by saidspindle. Eisthe bolstertube. Fisthe external supporting-tube, and f isthe horizontal transverse web connecting the two, these three partsbeing formed preferably in one casting or piece. I is the chamberedscrew or bolt by which the supportingtube iS held to the rail.

Itively to the other. thin and elastic to permit it to be thusde- -thespindle is caught fby the annular cup or groove e2 in the top ofthebolster-tube, and is thence returned to the oil-chamber within thesupporting-tube and the chambered screw by a passage, e3, formedin thewall ofthe bolster- Ytube and opening into the said chamber below theweb f.

The whirl C iS attached by a hub, G,to the spindle B. Above it andencircling the spindleis a bobbin-carrying sleeve, J. This sleeve isfast at its lower end to the spindle or to the hub of the whirl. It ispreferred to cast or otherwise form said Sleeve and whirl in one piece,and this is the construction shown in the drawings. rI`he sleeve abovethe point where it joins the whirl does not closely fit the spindle, butloosely encrcles it, there being between the two an annular space, whichwill permit the one to be laterally deflected rela- The sleeve issufficiently flected. Upon this sleeve the lower end of the bobbin fitsand takes its bearing, the bearing-surface j for the bobbin beingpreferably formed at the upper end of the sleeve. Under this arrangementit will be noted that the bot- ICO tirely; but, as hereinbefore stated,the bobbincarrying sleeve and its spindle can be made use of incombination with spindle-bolsters of other kinds, although, it isbelieved, not With equally good results.

Having described these improvements and the preferred Way of carryingthe same into effect, what is claimed herein as new and of the inventionof the said JOHN D. COLBY is as follows:

l. The combination,with the spindle, of the bobbin-carrying sleeverigidly secured at its lower end to said spindle and above that pointthroughout its length encircling the spindle loosely, so that the onemay be capable of lateral deiiection with respect to the other,substantially as and for the purposes set forth.

2. The combination,Wit-h the spindle and the bobbin, of thebobbincarrying sleeve loosely encircling said spindle, so as to permitthe lateral deiiection of the one with respect t0 they other, andfurnished with a bobbin-bearing at or near its upper end, as and for thepurposes described.

3. The combination of the spindle and its attached bobbin-bearing sleeveloosely encircling said spindle, so as to permitlateral deflection ofthe one relativelyto the othervith the bolster-tube, the supportingtube,and the transverse web connecting said tubes, substantially as and forthe purposes hereinbefore set forth.

4. The supporting-tube F, the bolster-tube E, extending above thesupporting-tube, and the transverse web f, connecting the two andclosing the top of the supporting-tube, in conibination with the spindleand its attached Whirl placed over the web and around the upper exposedportion of bolster-tube, these parts being constructed'and arrangedtogether, as hereiubefore shown and specified.

In testimony whereof I, EVA COLBY, administratrix of the estate of JOHND. CoLBY, (deceased,) have hereunto set my hand this 15th day ofOctober, 1886.

EVA COLBY.
